I likes the sound of the CON vs 5% trade off. I'll also double check the Troubadour's stats, I must have missed some numbers that should've gone into CON. But I'm also of the opinion of not giving more growth in exchange for the bonus stats, as that is supposed to be characteristic of the Lords, reflective on how Marth or Ike would start off fairly unimpressive but then blossom into some of the best non-mounted units in the game, if not THE best (non-mounted). (Moreso Marth from 1 and 3, not 11 and 12)
Also, about your concern with Sanctuary's lack of bully potential...well, I do have a LITTLE teaser for the upcoming GM Handbook/Beastiary: Enemy units get little buffs to their abilities, ESPECIALLY if they're bosses. For instance, Boss Bishops "lose" Sanctuary, and instead get...
Inquisition
Activated Effect
On their turn, a character with this skill can set up a zone 3 spaces in all four directions around the character. Anyone within this zone cannot exit, but anyone outside the zone cannot enter. As well, attacks from outside the zone cannot pass through to target anyone within. Attacks from inside the zone cannot go outside the zone, but attacks made against legal targets within the zone are permitted. Long range Healing staffs can also leave the zone, but Debuff and Buff staffs cannot. While the zone is active, character who activated this skill must continually use their action to maintain it; if they do not, the zone falls at the end of their phase.
(first draft)
This skill is also given to Inquisitor bosses in place of Benediction, because it just wouldn't seem right to not have the two go together (and I also couldn't think of a better thematic opposite to Sanctuary). And also because GM's publicly making called shots for the boss is, while remarkably honest, still pretty bullshit.
*guilty cough*
Oh! And those weapon icons? I really like them! I might use them in the book, maybe, not entirely sure. I do know the next (1.4 or 1.3something) is going to include a section detailing some of the more unique weapons (Why does a Claymore have 1-2 range for a Sword? Because it's a Big F'KING Sword. What the crap is White Lightning and why is it effective vs Dragons? Because if at first you don't succeed,
zap them with your Blue Eyes again! Among others)
